Figure 1.

(A) Neighbor-joining tree generated from Kimura two-parameter distances of cytochrome-b haplotypes from throughout the range of C. rubrigularis rooted with haplotypes from Carlia rhomboidalis. Branch lengths are shown above major internodes. Circles denote paired rainforest and open forest sites where both mtDNA and phenotypic variation was measured (closed circles = rainforest; open circles = open forest). Closed squares represent sites from which additional mtDNA sequences were obtained. (B) Map of the Wet Tropics showing sampling localities. Symbols are defined as above. (C) Box plots illustrating differences in snout–vent length (SVL) in C. rubrigularis between rainforest (c) and open forest (o) sites. BMC refers to the Black Mountain Corridor.
